摘　　要： 综述了目前不饱和聚酯(UPR)改性研究的最新进展。介绍了UPR增韧改性的方法,包括分子结构改性、互穿网络结构增韧改性UPR、基于第二相材料共混改性;讨论了含磷阻燃剂和无卤阻燃剂对UPR的影响;综述了低收缩研究发展的4个阶段。并指出了UPR改性中存在的问题和发展方向。 Research advances in modification of unsaturated polyester resin （UPR） were reviewed. The toughened modification processes of UPR were introduced, including changing monomer structure modification, forming IPN structure of UPR with other polymer, blending with the second phase materials.The effects of phosphor-containing flame retardants and halogen free flame retardants on unsaturated polyester resin were also discussed. Then some problems existed in modification of unsaturated polyester resin and the development direction were also pointed out.
